Choosing a Scenario

Depending on the configuration choices you make and version of the operating system
you choose, you can have different levels of CPU control. All aspects of
CPU control described in this chapter are dependent on the resource group property
RG_SLM_TYPE being set to automated.

Table 10-1 provides a description of the different configuration scenarios available.

Fair Share Scheduler

The first step in the procedures to assign CPU shares to resource groups
is to set the scheduler for the system to be the fair share
scheduler (FSS). By default, the scheduling class for the Oracle Solaris OS is
timesharing schedule (TS). Set the scheduler to be FSS to have the shares
configuration take effect.

You can create a dedicated processor set regardless of the scheduler class you
choose.
